As a result of detailed functional analysis of the novel transporter lysosomal multivitamin transporter 1 (LMVT1), the pyridoxine transport mediated by LMVT1 was driven by cotransport with protons. It was suggested to play a role in supplying pyridoxine from lysosomes into the cytoplasm, suggesting that it may be involved in the excretion and transport of various vitamins including pyridoxine from lysosome in an acidic environment to cytoplasm in a neutral pH environment. In addition, when the substrate recognition of LMVT1 was investigated, it was found that LMVT1 also transports compounds other than vitamins (drugs and bioactive substances). Taken these finding, LMVT1 may be involved in the regulation of pharmacokinetics and various physiological functions.
